Keywords: copper slag, copper slag flotation tailings, leaching, sulphuric acid, ferric sulphate, hydrogen peroxide Introduction The pyrometallurgical processing of copper concentrates generates large amounts of coppercontaining slag. Management options for this slag include recycling, recovery
Copper Smelting Slag Recycling Processing Line From the picture of the raw smelting slag, there are coarse copper and also fine copper granules, and by jigging, the copper granules can be recycled efficiently and the recovery is high, so the copper recycling flow sheet can be crushingscreeningjigging or shaking table separationdewatering.

Gyurov made copper slag oxidation decomposed under pure oxygen system, got different oxidation products at different temperatures and then recycled. 9) Kim used petroleum coke as the reducing agent, reduced copper slag under 1250°C, made reduction product brokenmagnetic separation, and got the final magnetic products (iron, more than 65 wt.%). 10) Langberg and Tarasov use gas mixture of ...
Keywords: copper, slag, sulphation, roasting, acid baking, leaching Introduction The environmental burden of waste disposal and decreasing metal ore grades make a strong case for implementation of alternative processes for metal recovery and metal recycling (Ochromowicz and Chmielewski, 2010; Schlesinger et al., 2011; Frandegard
ONSITE SLAG RECYCLING. Slag processing, or also referred to as bottom ash recycling or IBA recycling, and metal recovery on your site are the first steps in the range of services that Recco offers. We engineer and manufacture a customized installation for temporary processing built up and installed from modular machinery or install a permanent system.
Copper smelting slag is a solution of molten oxides created during the copper smelting and refining process, and about million tons of copper slag are generated annually in Korea. The oxides in copper smelting slag include ferrous (FeO), ferric oxide (Fe2O3), silica (SiO2 from flux), alumina (AI2O3), calcia (CaO) and magnesia (MgO). The main oxides in copper slag, which are iron oxide .

water recycling to the flotation stages. ... and to a copperrich slag. The two ore types can be smelted together to produce matte and a slag with low copper content. Another product is top gas, which contains flue dust. ... modern combined continuous casting/rodrolling systems already have sufficient temperature, thus saving thermal energy.

The slag from the TBRC would, of course, be recycled back to the DCarc furnace, in order to prevent the blown cobalt from being lost. In the case of copper reverberatory furnace slag, mineralogical studies showed that the cobalt is present as CoO. Copper in the slag is mainly attributed to the presence of copperrich sulphides.
Recycling of tellurium via copper smelting processes . In the matteslag system, by far most of the tellurium was vaporized into the gas phase, which is evident when combining the concentrations in matte and slag phases.
Copper slag is a byproduct obtained during the matte smelting and refining of copper. Singapore imports huge amount of copper slag to be used as abrasive material for ship clearing and repairing, and resulting in used copper slag as waste material. It has been estimated that 300,000 tonnes of copper slag needs to be disposed annually.
